Interesting Article in Planetcitizen About Sustainable Bulding Materials

Scientists in Spain and Scotland found that simply adding wool and a natural polymer found in seaweed to the clay of a brick makes it 37% stronger, and more resistant to the cold wet climate often found in Britain.

Another innovation comes from the world of concrete production, which accounts for a staggering 7-10% of global carbon dioxide emissions. When producing sustainable concrete crushed glass can be added, as can wood chips or slag - a byproduct of steel manufacturing. Whilst these changes aren’t radically transforming concrete, by simply using a material that would have otherwise gone to waste, the CO2 emissions associated with concrete are reduced.
